This is not a 100% duplicate since issue 88776 covers only
# Internal Error (53484152454432554E54494D450E435050020F), pid=2892, tid=3696
It has nothing about
# EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0xac000bb6, pid=1288, tid=4052
The latter one was also reproduced with dynamic attach to JBoss 4.0.5 GA.

If you believe that those JDK crash logs are caused by different bugs, you
should file separate issue for each of them. Closing as duplicate based on the
second JVM crash log.

I cannot reproduce it with
Profiler 070711
Windows XP version 5.1 running on x86; Cp1252; en_US (nb)
JDK 1.6.0_02
Mozilla Firefox 2.0.0.4
Closing as works for me. Please reopen if you can still reproduce it.
